Specification of Letters Patent.

Application led .Tune 29, 1911.

To all 'whom t may concern Be it known that I, Vieron H. SLINAGK, a citizen of the United States, and a resident of Philadelphia, in the county of llhiladel phia and State of Pennsylvania, have invented a certain new and useful Inverted incandescent Gras-Light, of which the following is a specification.

rthe principal object of the present invention is to provide a comparatively simple, durable and reliable hanging lamp for lighting inverted mantles by means of gas under considerable pressure and which shall in operation produce an extremely brilliant and steady light without becoming unduly heated.

@ther objects will appear from the following description taken in connection with the accompanying drawings forming part hereof, and in which Figure 1, is a side view principally in cen tral section, illustrating a light embodying features of the invention and provided with one burner. Fig. 2, is a similar view illustrating a modification of the invention and showing a light provided with two burners, and F ig. 3, is a sectional view illustrating a detail of construction embodying a modification of the invention.

1n the drawings 1 is a casing having the usual reflector c, and provided at its top with a ventilator 2 and having a double side wall 3 4, and a bottom wall 6 connecting` the said side walls and provided with air inlets 5 to constitute an air supply chamber which is of generally annular form and surrounds the body of the lamp.

7, is a globe arranged beneath the outer wall e, with air inlet space 8 above it and below the bottom wall 6.

9, is a deflector or baffle plato having a burner opening and an encircling hood 10, and both the deflector and hood are arranged beneath the inner wall 3 with space 11 between t-hem.

12, is a gas pipe which carries a yoke 13 having arms which support the casing and also brackets lll that carry the wall (S, the hood 10 and the brackets 15 from which the deflector 9 is suspended.

Referring more particularly to Fig. 1, 16 is a fitting carried by the gas pipe and pro vided with an air mixing tube 17, having an inverted mantle 18 depending through the b urner opening in the deflector and said fitting is also provided with a jetorihce 19, lwhich may be removable, and discharges into said tube and with an air intake chamber 20 communicating with the space between t-he double walls of the casing and inclosing the jet orifice and mixing tube.

21, is a shutter which may be turned from the outside of the casing and which serves to admit more or less air from the space between the double walls of the casing to the interior of the chamber 2O and to the mixing tube 17. rlhe shutter may be removed and access had to the section Q2 that carries the jet orifice, so that it can be unscrewed and removed so as to be cleaned.

23 are dirt catchers arranged in the fitting and they serve to insure a clean supply of gas to the jet orice 19.

The arrangement shown in Fig. 2, is substantially the same as has been described, except that a double fitting 1G is employed instead of a single one and it contains the gas cleaner or dirt catcher 23e, which can be removed for cleaning without disturbing the other parts.

The arrangement shown in Fig. 3, is sul stantially the same as has been described. more particularly in connection with lfig. 1. However in Fig. 3, the fitting 1Gb, is straight and not provided with elbows so that gas from pipe 12, passes through the cleaner 23'), and thence to jet 19 which is shown as formed in a plug screwed into the fitting.

ln the constructions of Figs. 1, 2, and El, the fitting is carried from the end of the gas pipe.

211, is a deflector arranged above the fitting and carried by the gas pipe.

25, is a pilot light tube which is provided at its lower end near the mantles with a perforated screen 26, which protects the small pilot light flame from. being extinguished by draft.

27, is a globe ring hinged at 28 and provided with a latch 29 cooperating -with a keeper 30. This latch is capable of manipulation by one hand and by reason of the construction of the latch and its keeper this can be done even when the globe is hot.

Pure air uncontaminated by products of combustion enters at 8 and iinpinges upon and is divided by the hood l0, which also protects the inantles and burners from direct drafts. Part of the air rises through the openings and reaches the annular inclosure around the casing and from this inclosure air is admitted in desired or properly regulated quantity past the shutter 2l, to the chamber Q0, and thence to the air and gas mixing tube 17. Part of the air circulates into the globe and keeps it cool and rising, supplies the mantles, and with the products of combustion escapes at the ventilator. The described circulation of air continues as long as the lainp or light is burning and thus properly supports combustion and keeps the parts troni being over-heated.

rihe part 16, hereinabove called a fitting, is an element through which gas passes and Which is provided With a lateral hole in which the section 22, is detachably inonnted as by u screw thread connection. The section is provided With the oriiice 19. By reinoving part 2l. the section 22, can be Withdrawn through the side Wall oi;1 the ainp casing Without disturbing the other parts of the lamp.

1Whatl claim is:

l. in inverted incandescent gas light coinprising the combination ot' a casing provided with a ventilator and having a double Wall constituting an air supply chainber, a globe beneath the enter part orn the double Wall with air inlet between it and the bottoni of said outer part ot the double Wall, a detlector having a burner opening and having a hood encircling the detlector with space between and both arranged beneath the inner part 01"' the double Wall, a gas pipe, and a fitting carried by the ges pipe and provided Wit-h an air and gas mixing tube having an inif'erted mantle depending through the burner opening, and provided with a jet oriiice discharging into said tube and provided With an nir intake chamber communicating with the air supply chainber and inclosing the orifice and mixing tube and forming an annular air chamber co-extensive With the in'fting tube7 substantially as described.

2. in inverted incandescentgas light coinprising the combination ot a casing provided with ventilator and having a double side ivall and a perforated bottoni Wall connecting the side Walls and constituting an air supply dninibe:7 a globe beneath trie outer Wall 1with air inlets between it and the bottoni Wall of the casing7 a b "'le plate arranged at 'the een r or" the casing, having a burner opening and hood encircling the bridle plate with space between tor the passage of products ot combustion and nir and both arranged beneath the inner Well, a gas pipe, and e r'itting carried by the gas pipe and provided With un air and gas mixing tube having an inver ed inantle depending through the burner opening, and provided with a jet orniee dischai ging into said tnbe and provided with an air intalre chaniber coinniunicating with the space between the double Wall and inclosing the jet orifice and mixing fori `ng an annular' air chai;-

)er concentric and co-extens' ,fe with the mixing tube., substantially as described.

in testimony whereof' l have hereunto sigiied iny nanie.
